Trucks hauling water from Missouri River to Ogallala Aquifer

A truck-load of water is traveling nearly 400 miles to keep the largest underground reservoir in the U.S. from drying up.

6,000 gallons of water from the Missouri River are being taken to two different locations to replenish the Ogallala Aquifer in the Great Plains. The aquifer is essential for irrigation in this high-producing region, and right now, some farmers who use the source are facing dangerously low levels.

Kansas state water authorities issued a permit for the movement of water. Some critics say it would be more efficient to tell producers to cut back on use.
